PyCharm 4.0.4 Help

Keymap:

Types of Breakpoints

PyCharm lets you create breakpoints of several types. Each breakpoint type supported by
PyCharm addresses different debugging needs and has its own individual settings.

Breakpoints are triggered when the program reaches the specified line of source code, before it is
executed.
The line of code that contains a set breakpoint, is marked with a red stripe; once such line of code is
reached, the marking stripe changes to blue.

Once set, a breakpoint remains in project until removed. Breakpoints can only be set on executable
lines of code. Comments, declarations of
methods, and empty lines are not valid locations for breakpoints.

If a file with breakpoints has been modified externally, for example, updated from a version control
repository, or changed in an external editor, so that line numbers are changed, then the breakpoints
will be moved accordingly.

It is important to note that PyCharm should be running at the moment of such modification;
otherwise, such changes will pass unnoticed.

Python Line Breakpoint

These breakpoints are assigned to lines of source code and are used to target a particular section
for debugging.

Temporary line breakpoints

These breakpoints are assigned to lines of source code and are used to target a particular section
for debugging. When hit, such breakpoints are immediately removed.

Django Line Breakpoints

These breakpoints are assigned to the lines of the Django templates, and can only be set on the lines
that
contain Django tags. Plain HTML lines in Django templates are not valid location for the Django line
breakpoints.

Django line breakpoints are triggered when the corresponding tags are rendered by the Django template
engine. Refer to the section
Debugging Django Templates
for details.

Exception Breakpoint

Exception breakpoints are triggered when the specified exception is thrown. Unlike the line breakpoints,
which require specific source references, exception breakpoints apply globally to
the exception condition, rather than to a particular code reference.

Depending on the type of processing an exception, the debugging can break when a process terminates with
an exception, or as soon as an exception occurs.

Django exception breakpoints enable suspending the program execution when a Django template error occurs
(exceptions
TemplateDoesNotExist
orVariableDoesNotExist),
if such a breakpoint is enabled in the
Django exception breakpoints
tab of the
Breakpoints
dialog.

JavaScript Breakpoints

JavaScript breakpoints are the line breakpoints assigned to particular lines of JavaScript source code.
They can be set in
*.html
and in
*.js
files,
and are used to target a particular section of code for debugging.
